X Cube AI Internal Error: Trying to remove _lstm_layer_detail_LSTM_output_1 which has multiple inputs

[ERICWU]

Hi,

I tried to deploy a LSTM model on stm32h747i-disco board. However, I met "
INTERNAL ERROR: Trying to remove _lstm_layer_detail_LSTM_output_1 which has multiple inputs" when I used x-cube-ai to analyse the model. 

I am wondering what should I do to solve this problem and why it has this problem.

Thanks.
